Further, participants with larger position-dependent differences in movement availability tended to initiate correct sequences faster and with a higher temporal accuracy. Our results suggest that competitive preactivation is established gradually during sequence planning and predicts sequence skill, rather than the temporal structure of the motor sequence.NEW & NOTEWORTHY Sequence planning is an integral part of motor sequence control. Here, we demonstrate that the competitive state of sequential movements during sequence planning can be read out behaviorally through movement probes. We show that position-dependent differences in movement availability during planning reflect sequence preparedness and skill but not the timing of the planned sequence. Behavioral access to the preparatory state of movements may serve as a marker of sequence planning capacity.Neural codes for sensory inputs have been hypothesized to reside in a broader space defined by ongoing patterns of spontaneous activity. To understand the structure of this spontaneous activity in the olfactory system, we performed high-density recordings of neural populations in the main olfactory bulb of awake mice. We observed changes in pairwise correlations of spontaneous activity between mitral and tufted (M/T) cells when animals were running, which resulted in an increase in the entropy of the population. Surprisingly, pairwise maximum entropy models that described the population activity using only assumptions about the firing rates and correlations of neurons were better at predicting the global structure of activity when animals were stationary as compared to when they were running, implying that higher order (3rd, 4th order) interactions governed population activity during locomotion. Taken together, we found that locomotion alters the functional interactions that shape spontaneous population activity at the earliest stages of olfactory processing, one synapse away from the sensory receptors in the nasal epithelium. These data suggest that the coding space available for sensory representations responds adaptively to the animal's behavioral state.NEW & NOTEWORTHY The organization and structure of spontaneous population activity in the olfactory system places constraints of how odor information is represented. Using high-density electrophysiological recordings of mitral and tufted cells, we found that running increases the dimensionality of spontaneous activity, implicating higher order interactions among neurons during locomotion. Behavior, thus, flexibly alters neuronal activity at the earliest stages of sensory processing.The development of therapeutic regenerative medicine and accurate drug discovery cell-based products requires effective, with respect to obtaining sufficient numbers of viable, proliferative, and functional cell populations, cell expansion ex vivo. Unfortunately, traditional cell culture systems fail to recapitulate the multifaceted tissue milieu in vitro, resulting in cell phenotypic drift, loss of functionality, senescence, and apoptosis. Substrate-, environment-, and media-induced approaches are under intense investigation as a means to maintain cell phenotype and function while in culture. In this context, herein, the potential of macromolecular crowding, a biophysical phenomenon with considerable biological consequences, is discussed.Integrating sex as an important biological variable is imperative to enhance the accuracy and reproducibility of cell-based studies, which provide basic information for subsequent preclinical and clinical study designs. Tween 80 clinical trial Recently, international funding agencies and renowned journals have been attempting to integrate sex as a variable in every research step. To understand what progress has been made in reporting of cell sex in the articles published in AJP-Cell Physiology since the analysis in 2013, we examined the sex notation of the cells in relevant articles published in the same journal in 2018. Of the 107 articles reporting cell experiments, 53 reported the sex of the cells, 18 used both male and female cells, 23 used male cells only, and 12 used female cells only. Sex omission was more frequent when cell lines were used than when primary cells were used. In the articles describing experiments performed using rodent primary cells, more than half of the studies used only male cells. Our results showed an overall improvement in sex reporting for cells in AJP-Cell Physiology articles from 2013 (25%) to 2018 (50%). However, sex omission and male bias were often found still. Furthermore, the obtained results were rarely analyzed by sex even when both male and female cells were used in the experiments. To boost sex-considerate research implementation in basic biomedical studies, cooperative efforts of the research community, funders, and publishers are urged.Objectives Self-inflicted facial gunshot wounds (GSWs) result in complex but consistent injuries that are often survivable. We suggest a novel method for rapid stratification into groups that may be associated with hospital course and cost after self-inflicted facial GSWs. Methods This is retrospective review of self-inflicted facial GSWs between January 1, 2009, and December 31, 2018, at a tertiary academic center. Patients were given a penetrating trauma rapid estimated disablity (PRED) score (1-4) based solely on radiologic imaging injury patterns. Clinicopathologic factors were then compared between groups. Results There were 2 PRED 1 patients (15.1%), 8 PRED 2 patients (29.6%), 5 PRED 3 patients (18.5%), and 12 PRED 4 patients (44.4%). An increased PRED score was statistically associated with increasing mean days in intensive care unit (2.5 PRED 1, 4.2 PRED 2, 6 PRED 3, 11.6 PRED 4, p = 0.001), mean length of hospitalization (5.5 PRED 1, 13.1 PRED 2, 25.6 PRED 3, 39.8 PRED 4, p = 0.007), and mean cost ($) of hospitalization (22,000 PRED 1, 29,000 PRED 2, 37,000 PRED 3, 63,000 PRED 4, p = 0.01). Conclusions and Relevance The PRED score for self-inflicted GSWs to the face is strongly associated with length of hospital stay and cost of hospitalization.
